ABSTRACT
This study analysed pattern of growth of the lens by measuring the lens surface area, circumference and diameters in relation to the eye ball in albino rat at ten stages, 12, 13, 14, 16, 18 and 20 days of embryonic development and 1, 7. 14 and 28 days of post-natal development. We used the recent technique DIAD [Digitizing and Image Analyzing Device] and runing the autocad program. Surface area of the lens increases during different stages of development and reachs its maximum percentage in relation to the eye ball during the 4[th] and 5[th] stages. Surface area of the lens at 10[th] stage is more than 60 folds than the 1[st] stage. Transverse diameter of the last stage is more than 8 times of the first stage. Anteroposterior diameter is nearly equal the transverse diameter up to the 5[th] stage then it declines. Significant age-related linear increas were found for all parameters
